some of our customers using non-HMS Profinet fieldbus interfaces have station names starting with ‘+++’. This seems to be not supported by Anybus CompactCom (Network Configuration Object 0x4, Instance #20, Station Name : “…Labels consist of [a-z, 0-9, -]…”). We made tests using PRONETA tool which generates an unusual string, see attached screenshot. Our visualized result showing ‘xnxnxn123…’, obviously replacing the ‘+’ by ‘xn’ is also traceable by Wireshark.
My question is if there is any possibility how to manage such special characters in a different way?
